TI-25 Vintage Calculator

The TI-25 was my calculator in school. It was produced in 1978. This app is a simulation of it. The many years of use has left some scratches on the surface, but it is still going strong. Here you can try it out and get an almost to real look and feel of it. The simulation takes into account many of the not so charming features of the original.
The time for calculating is quite long and the correctness is not impressive either. There are however settings that you can use if you want to improve it, but of course that would take away some of the nostalgia.
In spite of the shortcomings mentioned, I really appreciated it and it was a very good friend of mine for many years.
I hope you enjoy it as much as I do!
